I noticed my neighbor's rooster in my yard this morning. When I went out to check on my chickens a little later, I noticed my Roo just sleeping on the grass. When I approached him, he didn't move. That is when I noticed that he can't open his eye. I'm too afraid to try to open it because I don't want to see what it looks like. But now I think he & my neighbor's roo probably fought & either his eye is gone or injured so badly he can't open his eye. I have moved him to where my neighbor's Roo can't get him. And it just seems like all he wants to do is lay down & sleep. Has anyone ever had anything like this happen? And is there anything I can do to treat it?
